Determining the toughest level in Candy Crush Saga can be subjective, as it often depends on individual player skills and strategies. However, several levels are frequently mentioned as particularly challenging.

Level 13907 is often cited as one of the hardest levels in Candy Crush Saga. This level requires strategic planning and the use of boosters to complete.

Level 4223 is noted for being difficult to clear but particularly challenging to score three stars or sugar stars. To achieve three stars, players need to score over 10 million points, which requires precise moves and efficient use of special candies.

Levels like Level 245 and Level 255 are also mentioned as being extremely difficult. Players often report getting stuck on these levels due to limited moves (19 moves for Level 245 and 14 moves for Level 255) and the need for strategic planning and booster usage.

While specific levels may be particularly tough, some general strategies can help players navigate through challenging levels:

1. Boosters: Boosters can significantly aid in clearing the board. Each booster has a unique effect that can be crucial in specific situations.

2. Special Candies: Creating special candies can help clear large areas of the board quickly.

3. Blocking: Using blockers strategically can prevent opponents from making moves and create opportunities for your own moves.

4. Replaying Levels: Some players use the strategy of replaying levels until they get a “lucky” board, although some levels have become “legendary” levels that require more effort to complete.

5. Gold Bars: Winning episodes or participating in community contests can earn gold bars, which can be used to purchase boosters or extra moves when needed.

In summary, while there isn’t a single “toughest” level that applies universally, levels like 13907, 4223, 245, and 255 are frequently mentioned as particularly challenging. Mastering the use of boosters and special candies, as well as employing strategic blocking techniques, can significantly improve a player’s chances of success in these difficult levels.
